I was on the beach everyday when I was in Spain, and of course I took so many bikinis. This polka dot bikini is one of my favourite bikinis out of all of them. I ordered this one from eBay, £30.
I'm not quite into the colour pink, but I do think that if you know how to ware it or if it's mixed with other colours, you can make it look quite cool. Like in this case, black and hot pink looks great, and I'm gonna tell you that no one had a bikini like this on the beach.
I'm afraid I couldn't find these ones online but I'm quite sure you can get similar ones all around the stores in London.
